Fig. 13
The treatment coverage (TC) is depicted as a 2D heatmap via changing two factors: the awareness (A) on the x-axis and the vaccine efficiency (η) on the y-axis. The first, second, and third rows in this figure indicate the outcome of changing the testing costs for (a-*) C_t=0.1, (b-*) C_t=0.5, and (c-*) C_t=0.9. Along with that, the first, second, and third columns indicate the outcomes of adjusting the vaccine cost rate: (*-i) C_v=0.1, (*-ii) C_v=0.5, and (*-iii) C_v=0.9. The treatment coverage reaches its peak level when testing costs are low. On the contrary, the ultimate level of treatment coverage is reduced when testing cost is high. The remaining parameters are: ϕ=0.5,β=1.0,γ= 0.1,m=0.2.
